In this study analysis and design procedures of partially compliant mechanisms using two degree of freedom mechanism model are developed. The flexible segments are modeled as revolute joints with torsional springs. While one freedom is controlled by the input to the mechanism, the motion of the parts are governed both by the kinematics and the force balance. The procedure developed for the analysis of such mechanisms is shown on two different mechanisms: a five link mechanism with crank input and slider output (five-bar mechanism); a five link mechanism with crank input and rocker output. Design charts are prepared according to output-link oscillation and dimensionless design parameters.

On the design of a novel fully compliant spherical four-bar mechanism Parlaktaş, Volkan; Tanık, Engin; Tanık, Çağıl Merve (SAGE Publications, 2019-9) <jats:p> In this article, a novel fully compliant spherical four-bar mechanism is introduced and its generalized design methodology is proposed. The original fully compliant mechanism lies on a plane at the free position (undeflected position); therefore, it has the advantages of ease of manufacturing, minimized parts, and no backlash. First, the mobility conditions of the mechanism are obtained. The dimensions of the mechanism are optimally calculated for maximum output rotation, while keeping the deflecti...
On efficient use of simulated annealing in complex structural optimization problems Hasançebi, Oğuzhan (Springer Science and Business Media LLC, 2002-01-01) The paper is concerned with the efficient use of simulated annealing (SA) in structural optimization problems of high complexity. A reformulation of the working mechanism of the Boltzmann parameter is introduced to accelerate and enhance the general productivity of SA in terms of convergence reliability. Two general and complementary parameters, referred as "weighted Boltzmann parameter" and "critical Boltzmann parameter," are proposed, Several alternative methodologies are suggested for these two parameter...
Development of test structures and methods for characterization of MEMS materials Yıldırım, Ender; Arıkan, Mehmet Ali Sahir; Department of Mechanical Engineering (2005) This study concerns with the testing methods for mechanical characterization at micron scale. The need for the study arises from the fact that the mechanical properties of materials at micron scale differ compared to their bulk counterparts, depending on the microfabrication method involved. Various test structures are designed according to the criteria specified in this thesis, and tested for this purpose in micron scale. Static and fatigue properties of the materials are aimed to be extracted through the ...
Analysis and design of a compliant variable stroke mechanism TANIK, ENGİN; Söylemez, Eres (Elsevier BV, 2010-10-01) In this paper, analysis and design of an underactuated compliant variable stroke mechanism are presented by employing its pseudo-rigid-body model (PRBM). During the design two cases are considered: prescribed output loading and constant input torque. It is shown that this mechanism is suitable where variable stroke is required corresponding to variable output loading. It is also observed that this mechanism is capable of providing nearly constant force over a wide range of input. The analysis and design app...
Design of compliant mechanisms for industrial applications Yilmaz, Alikan; Söylemez, Eres; Department of Mechanical Engineering (2013) Compliant mechanisms have the advantages of simplification in manufacturing and assembly, reducing cost, weight, wear, backlash and noise owing to their intrinsic structures. The aim of this study is to develop optimization methods to design reliable, high performance and easily manufacturable compliant equivalents of rigid body mechanisms used in industrial applications by utilizing the advantages of compliant mechanisms over rigid body mechanisms. Two particular mechanisms from the industry, namely a bist...
